b) ing Appendix AAnswers to the Review Questions Chapter 1: Motherboards, Processors, and Memory A. The spine of the computer is the system board, otherwise known as the motherboard. All other computer components plug into the motherboard. On the motherboard, you will find the CPU, underlying circuitry, expansion slots, video components, RAM slots, and various other chips. C. DDR4 SDRAM is manufactured on a 288‐pin DIMM, as is DDR5 (although the two are keyed differently and are not compatible). DIMMs with 224 pins and 296 pins do not exist. DIMMs with 240 pins are used for DDR2 and DDR3 SDRAM. B. Remember the 8:1 rule. Modules greater than but not including SDR SDRAM are named with a number eight times larger than the number used to name the chips on the module. The initials PC are used to describe the module; the initials DDR are used for the chips; and a single‐digit number after PC and DDR is used to represent the level of DDR. The lack of a single‐digit number represents DDR as long as the number that is present is greater than 133 (such as PC1600). Otherwise, you're dealing with SDR (such as PC133). This means that PC3‐16000 modules are DDR3 modules and are populated with chips named DDR3 and a number that is one‐eighth of the module's numeric code: 2000.
